用停流分光光度计测定了5，7-二异丙基生育酚氧自由基（Toc）与儿茶素类（表儿茶素（EC）、表儿茶素没食子酸酯（ECG）、表没食子儿茶素（EGC）、表没食子儿茶素没食子酸酯（EGCG））及其相关化合物（没食子酸甲酯（MG）、4-甲基儿茶酚（MC）和5-甲氧基间苯二酚（MR））的反应速率（k（r））。k（r）值按MR的顺序增加
The reaction rates (k(r)) of 5,7-diisopropyl-tocopheroxyl radical (Toc(center dot)) with catechins (epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC), epigoallocatechin gallate (EGCG)) and related compounds (methyl gallate (MG), 4-methyleatechol (MC), and 5-Foethoxyresorcinol (MR)) have been measured by stopped-flow spectrophotorneter. The k(r), values increased in the order of MR
